14-8 PHYSICAL GEOGRAPHY 
lower. Blakestone edge, 1923 (N.), Whitea fell or Pickington ridge 
1855 (N.), Grinton Grits 1678 (N.), Robin Cross Hill 1407 (N.) All 
these are above the main limestone. In Sattron Hangers that rock is 
1776 feet high. 
The passes in this long mountain ridge, which I have measured, 
are the following. West of Lovely seat, the road from Muker to 
Hawes, (above the lower millstone grit), about 1760 feet; between 
Askrigg and Muker 1694 feet (on main lime), between Bolton and 
Reeth on beds below the middle millstone grit about 1500 feet, between 
Ley burn and Reeth on similar beds about 1000 feet. The main 
limestone at Leyburn inn is 700 feet above the sea. 
Between Wensleydale, Wharfedale, Coverdale, and Widdale, is a 
large tract of elevated ground, rising uniformly toward the south- 
west; parallel to the plane of the main limestone. Waldendale, 
Bishopdale, and the branching valleys of Simmerdale, divide this 
region into four principal groups and ridges, viz. the group of Snays 
fell. Cam, Dod, and Bear’s head : — the ridge of Stake and Addle- 
burgh ; — W asset fell ; — and the range from Buckden pike to Pen 
hill;— a fifth narrow region is on the escarpment edge over Wharfe- 
dale, between Cam fell and the head of Bishopdale. The height of 
the ground is proportioned to the position of the point on the in- 
clined plane of the strata, and the mass of grits, &c. above the limestone. 
Cam group — consisting of ramified Yoredale limestone, covered by 
three insulated patches of grit rocks. The main limestone in Cam 
fell 1924 feet (N.) In Bear’s head 1946. The grit summits of Dod 
fell 2184 (N.) Bear’s head 2019. Ten end 1919. 
Stake fell — (a little grit over the main lime) 1843 feet (N.) Ad- 
dleburgh capped by underset limestone? 1565 (N.) Summit of road 
from Bainbridge to Buckden 1901. 
Wasset fell— (grit on main limestone) 1876 feet (N.)
